With theabove object in view the disks side walls 11.: It being understood-thatthe other material fed into the housing upon .a

breaker plate .An important feature of this invention re-' sides inmeans for adjusting the relative po sition between the path traversed bythe faces of the hammers and the breaker plate, this is accomplished byslidably mounting the bears ing 88 of the shaft 26. The bottom faces 89of said bearings engagethe upper surfaces of lateral flanges or supports40 preferably;

formed integral with the side walls 12 of the housings, and are held inadjusted position by bolts 41 and nuts 42, the bolts extending throughslots 48 formed in the supports.

' Adj ustingrscrews 44 are mounted in thread ed openings in upstandinglugs 46 formed on each end of the supports 40 and engage the end faces48 of the bearings.

From the construction it will be seen that by loosening the nuts 42andturning the ad- 'ustin screws 44 a ver nick and accurate adjustmentbetween the hammers and plates may be obtained, also that it isnotnecessary to disassemble any part of the apparatus.

Breaker plate 86 is of square shape, and

- is mounted in a corresponding recess '52 formed 1n the end wall 14,and is retained 111 place by a tapered wedge or key 58.,disposed in anopening ina lug '54 formed on the underside, and in the center'of saidplate, the

46 lug projecting through an opening in the end wall 14. e

Due to the square shape and mounting of the breaker plate, it will beseen that after it has become worn across one end (i. e., the

- nearest to the path traversed by the hammers) it may be turned so thata new surface will be presented and so on until all four edges are worndown, thus permitting much longer use than is possible with the usualshape and mounting of these plates.

The apparatus is arranged to'classify or separate the material as it iscrushed. This is accomplished by providing the disks. and

hammers'with fan blades or vanes indicated at and 61 respectively, whichinduce a currentof air through the housing, the current of air picks upandcarries with it the fmely divldedpartlcles as the material iscrushed.

The air current thus produced'passes from v the housing intoa conduit 62provided with a'plurality of discharge openings indicated at 64, 65 and66, the conduit being secured to the curved top 16 of the housing by along radius elbow 68 in register with an opening 68 formed therein. Theconduit is of sufficient length to permit settling of the material, andis supported at a plurality of points throughout its length by standardsor the like indicated at 67. a

Air is admitted openings, 25, the passage of the air therethrough beingcontrolled by intermittently operated gates 70 alternately opening andclosing saidopenings, and is arranged as follows: 7 r

Framesdesignated at 7 2 are secured by cap screws or the like 78 to theinner faces of the bearings 88, quadrants 74 having: arms 76 and 77, andhangers 78 are pivotally mounted on' pins 80 projecting from the frame.The gates are connected by pins 81 to .the arms 7 6 of the quadrants 74,and by pins 82;to the hangers 78, the hangers 78 being provided tosupport the outer ends of the gates when in openposition. i The armscated ends 84 which engage the outer ends of pins'85 projecting fromblocks 86 formed on rods 87 slidably mounted in guide members 88 securedto the frames.

Rotatably mounted. in bearings 84 secured toupper ends of the frames isa shaft 90, the shaft-having eccentrics 91 thereon engaged by straps 92which in turn are con? neoted to the pins on the blocks. A sprocket 94issecured to the shaft, and is adapted to be connected by a chain (notshown) to 7 any suitable source of powerfor transmitting rotationto saidshaft.

It will be understood that means'other than the above described maybeemployedto operate said gates.

Referring snore specifically to Fig. 8, a

gate designated at 'is provided toregulate the amount of materialentering the apparatus. The gate is secured to a shaft 101 E mounted inbearings102 carried by'a cross bar 108 extending between. the side walls12 of the housing, the gate is held in adjusted position by an arm 104having'a clamping 1" bolt 105 extending through an arcuate slot 106formed in a bracket 108 carried by one of the bearings 102. V r v g Incrushing certain classes of material it maybe more desirable to make theadjustment of the hammers vertically rather than horizontally; suchadjustment is provided for by-the construction shown in Figs. 5 and 6,arranged as follows:

Vertically disposed fl 110 formed tegral with or secured to thesidewalls 11 are-engaged by flanges114'of members 115 upon which theshaft bearing 116'is mountto the housing through the 77 of thequadrantshave bifure ed. The member is held in'place by bolts 117extendingthrough slots 111 formed in the flanges 110, and openings inthe flanges 114.

In making an adjustment, a jack designated at 118 is preferablyemployed, the jack being placed under the member 115 with its screw headengaging the underside of the cross bar 119 of said member 115, it beingunderstood that during making such adjustment the nuts are loosenedsufliciently to permit movement of the member 115.

Operation of the improved crushing and separating apparatus is asfollows:

The shaft 26 is rotated in the direction indicated by the arrow A,material is fed into the housing through the opening 13, and passesunder the gate onto the breaker plate 36 whereon it is crushed by impactwith the hammers. The current of air induced by the fan blades 60 and 61picks up the finely divided particles of the materlal and carries themwith it into the conduit 62 wherein they settle on the bottom throughoutthe length thereof, the coarser or heaviest particles drop through theoutlet 64, the medium through the outlet 65, and the lighter or fineproduct passes through the outlet 66.

The volume of air admitted is regulated by movement of the gates 70, theaction of which also causes intermittent blasts of air which in turnaids settling and separation of the material in the conduit. In handlingmaterial which may be reduced to powder a plate indicated at P may beplaced over the grate as shown in Fig. 3.

I claim:

1. An apparatus of the character described comprising a housing, a shaftextending through said housing, bearings rotatably supporting said shaftat each end thereof, a plurality of disks secured to said shaft, aplurality of hammers pivotally mounted on pins extending between saiddisks, a horizontally disposed conduit having a plurality of outletsconnected to said housings with one end thereof in register with anopening formed in said housing, each of said disks and hammers having aplurality of blades formed thereon for inducing a current of air throughsaid housing and conduit, and means for controlling the current of airinduced by the fan blades on said disks and hammers.
